Definitions

  • the present invention relates to an apparatus for automatically filling a container with a post-mix carbonated beverage. More specifically, the present invention relates to an ultrasonic level detector for automatically controlling the filling of a container with a carbonated beverage which tends to form a head of foam thereon during the filling operation.
  • liquid level detector devices in these prior art systems generally utilize electrical probes such as conductive or capacitive probes to determine liquid level.
  • the use of ultrasound has definite potential advantages for the purposes of controlling an automatic filling operation of beverage cups in that the ultrasonic transducer may be utilized both for initiating the filling operation in response to detecting the presence of a cup and continuously monitoring the liquid level within the cup during the filling operation until a predetermined liquid level is achieved. Both of these functions can be achieved by mounting an ultrasonic transducer adjacent to a dispensing nozzle of the post-mix beverage dispenser without cluttering the area of the dispensing machine adjacent to the working area where the cup is to be disposed.
  • an automatic cup-filling apparatus utilizing an ultrasonic transducer for detecting the presence of a cup and automatically controlling the filling thereof to a proper height.
  • an apparatus for automatically filling a container with a carbonated beverage which tends to form a head of foam during the filling thereof including:
  • the liquid level detecting functions are performed by an ultrasonic transducer and associated transceiver circuitry and the control functions are implemented by a programmed microprocessor such as a Motorola MC6801.
  • a programmed microprocessor such as a Motorola MC6801.
  • the control operations of the present invention could be implemented with discrete logic circuits and components configured to perform the control functions of the present invention instead of utilizing a programmed microprocessor.
  • the opening of the dispenser valve and, therefore, the initiation of the filling operation, in accordance with the present invention is triggered by the proper positioning of a cup to be filled under a dispenser nozzle which has an ultrasonic transducer disposed adjacent to the nozzle.
  • the ultrasonic transducer transmits ultrasonic pulses toward the cup to be filled and ultrasonic wave energy is reflected from the cup lip, the cup interior,and support tray on which the cup is supported to provide the necessary data with respect to cup presence, position, and the level of liquid or ice therein.
  • the presence of a cup is determined by detecting the same lip signal for a series of lip level signals such as for 3 out of 4 pulses in the series, and initiation of a cup-filling operation is not permitted unless this occurs.
  • the identity of reflected signals is determined by the time of their occurrence, as compared to a pulse transmitted from the ultrasonic transducer. For example, a reflected signal from the cup lip reaches the transducer much faster than a signal reflected from the bottom of a cup. Accordingly, these signals are spaced in time along a time axis referenced to ultrasonic pulses transmitted from the transducer, and can be identified accordingly. Likewise, a signal reflected from the top of a quantity of ice in a container can be analyzed on such a time axis to determine the level of ice in the cup being filled. In accordance with the present invention, filling of the cup is precluded if the level of ice exceeds a predetermined limit prior to the initiation of the filling operation.
  • the present invention provides suitable detector curcuitry to detect the trailing edge of the lip signal and the trailing edge of the liquid level signal to avoid this ringing or overlap problem. Since a detectable trailing edge of a cup lip signal disappears when overlap occurs with a liquid level signal, the absence of the trailing edge of the lip signal is used to indicate that the liquid level has reached the cup lip.
  • FIG. 1 there is illustrated in front perspective a post-mix beverage.dispenser apparatus generally indicated 20.
  • the particular dispenser apparatus illustrated includes three dispensing nozzles 22 for dispensing three different types or flavors of soft drink beverages.

  • ultrasonic wave energy is transmitted from ultrasonic transducer 26 toward the cup 24 and reflects from the interior of the cup, the cup lip 24 L and the drip tray surface 28, back to the ultrasonic transducer 26 wherein it is processed in a'transceiver circuit to be described hereinafter in connection with Figure 2.
  • the ultrasonic signal reflected form the interior of the cup either reflects from the bottom of the cup or from the contents of the cup, which may be either ice or liquid, depending on the point within the automatic filling-cycle, and is labeled LL.
  • the ultrasonic signal reflected from the cup lip 24L is labeled CL
  • the ultrasonic signal reflected from the drip tray or grate 28 is labeled DT.
  • the cabinet of the post-mix beverage dispenser 20 of Figure 1 is also provided on the front surface thereof with an indicator light 32 which is illuminated when an operator attempts to fill a cup having an excess of a predetermined limit of ice.
  • the cabinet of the post-mix beverage dispenser 20 also houses the necessary syrup-packages, carbonator and control circuitry for operating dispenser valves which are in operative association with each of the dispenser nozzles 22.
  • These dispenser valves may be of any type conventional in the art which are, for example, electrically actuated and initiate the flow of liquid out of dispenser nozzles 22 when open and stop the flow of fluid out of those nozzles when closed. These valves are opened and closed in response to signals from the microprocessor 34 of the system of Figure 2, to be described hereinafter.
  • FIG. 2 there is illustrated a block diagram of the automatic filling apparatus of the present invention, including a microprocessor 34 which may be a Motorola MC6801.
  • the microprocessor 34 transmits trigger signals along bus line T to the transceiver driver circuit of the ultrasound transducer 26 and receives processed electrical signals from the reflected ultrasonic energy measured by ultrasound transducer 26 via line R.
  • the reflected signals received along bus line R are processed within microprocessor 34 in accordance with program logic functions in order to generate control signals along bus line C to operate the dispenser controls 20C within the post-mix beverage dispenser 20 of Figure l.
  • the dispenser controls include valves associated with each of the dispenser nozzles 22 for starting and stopping the flow of beverage from those nozzles into an associated cup to be filled.
  • the drive circuitry for the ultrasound transducer 26 includes a waveform generator 36, a driver amplifier 38, a pulse transformer 40 and a tuned RLC circuit 42. This drive circuitry is triggered to generate ultrasonic pulses from transducer 26, directed toward the cup 24 in Figure l.
  • the driver section of the transceiver circuit illustrated in Figure 2 supplies a sinusoidal 50KHz, 220 volt burst with a 150 volt D.C. bias to the transducer when triggered by a signal from bus line T from the microprocessor 34.
  • TTL Transistor-Transistor-Logic
  • each pulse represents reflected ultrasonic waves by the portion of the transceiver circuitry of Figure 2, including a buffer amplifier 44, a multiplexer 46, a first amplifier 48, a passive 60Hz filter 50, a second amplifier 52, a comparator 54, and a 50KHz filter 56.
  • the driver amplifier 38 may comprise a conventional NPN transistor 38 having its base connected to the output of waveform generator 36, comprising an oscillator with a 50KHz output.
  • the collector of the driver amplifier 38 is connected to a pulse transformer circuit 40, which is coupled within an RLC tuned circuit 42.
  • the collector is also coupled to ground through a protective diode Dl, which protects driver amplifier 38 from inductive overvoltages caused by switching the pulse transformer 40.
  • the tuned circuit 42 is conventional in the ultrasonic transducer art and provides coupling between both the driving and signal processing portions of the ultrasonic transceiver circuit.
  • the waveform generator 36 may be any commercially available, single-chip oscillator which generates three cycles of a 50 KH z TTL level signal when triggered along line T by the microprocessor 34 of Figure 2.
  • the pulse transformer 40 transforms a 5 volt input signal from the waveform generator 36 and driver amplifier 38 into a 220 Volt signal, suitable for driving the ultrasonic transducer.
  • the RLC tuned resonant circuit including elements R, L and C, has a very high q so that it effectively drives the transducer 26 and couples detected signals to the signal-processing portion of the transceiver circuit.
  • a 320 volt Zener diode Zl protects transducer26 from overvoltage.
  • the circuit of Figure 3 has been designed to minimize electrical "ringing", while still providing adequate signal-to-noise ratios.
  • FIG 4 there is illustrated a circuit diagram for the buffer amplifier 44, the first amplifier 48 and the 60Hz passive filter 50 of Figure 2.
  • This circuit is implemented with a commercially available integrated circuit chip which is a dual OP-Amp, Model Number LF353, manufactured by National Semiconductor.
  • the terminal pins illustrated in Figure 4 bear the commercial pin numbers provided on the manufacturer's data sheet and are numbered 1 to 8.
  • This dual OP-Amp configuration implements the combined functions of the buffer amplifier 44 and-48 illustrated in. Figure 2. Thas is, the buffer amplifier should have a unity gain in order to preserve the high q of the RLC circuit 42, and the first amp 48 in conjunction with a second amp 52 illustrated in Fig.
  • the passive 60Hz filter 50 is a simple RC filter used to eliminate stray 60 Hz power line noise from the amplified signals output from the first amplifier 48. It should be understood that the multiplexer 46 of Figure 2 may be interposed between the buffer amplifier 34 and the first amplifier 48, as illustrated in Figure 2, but since Figure 4 only shows one signal path for one transducer, the multiplexer 46 is eliminated for clarity.
  • FIG. 5 there is illustrated a detailed circuit diagram of the second amp 52 of Figure 2 and the comparator 54 thereof.
  • the functions of these elements are implemented again by a dual OP-Amp, commercially-available, integrated circuit chip LF353 manufactured by National Semiconductor and the commercial pin numbers 1 to 8 are illustrated in Figure 5.
  • the 5.1 volt Zener diode clamps the output of comparator 54 to a TTL compatible level.

  • This filter may be a type 74LS123 retriggerable one-shot circuit manufactured by Texas Instruments. The function of this filter is to remove any trace of the original 50KHz frequency generated by the waveform generator 36.
  • the input of this filter as illustrated in Figure 2, is connected to the output of the comparator 54 and the output is connected to the microprocessor 34 through bus line R.
  • a multiplexer 46 suitable for use in the block diagram of Figure 7, which may be a commercially-available IC chip, Model Number 4066, manufactured by National Semiconductor. As illustrated, this multiplexer may receive up to six inputs along commercial pin numbers 1 to 6 and output signal along terminals connected to commercial pin numbers 8 to 14 in a time share multiplex fashion, for operating up to six dispenser valves and associated nozzles.
  • the graphs A to E therein illustrate various conditions which might occur pursuant to the automatic filling of a cup with a post-mix beverage, as illustrated in Figure 1.
  • time is plotted along the abscissa and amplitude of the reflected ultrasonic signals along the ordinate.
  • the signals in Figure 8 show waveshapes of reflected signals seen by transducer 26 prior to being processed into TTL logic levels by the circuitry of Figures 3 to 7.
  • the microprocessor 34 sees square wave TTL signals positioned on the time axis at the same positions as the waveforms of Figure 8.
  • Graph A illustrates the nature of the reflected signals for an empty cup 24 supported on a drip tray 28 below a dispenser nozzle 22 in an ultrasonic transducer 26, such as illustrated in Figure 1.
  • the left-hand reference of the graph A labeled O, represents the point in time that a pulse is transmitted downwardly by ultrasonic transducer 26 in the configuration of Figure 1 toward the cup 24. Therefore, all of the reflected pulses are referenced to the generation of an associated transmitted pulse along a time axis t.
  • the reflected ultrasonic pulse signal from the cup lip 24L is labeled CL, and it reaches ultrasonic transducer 26 much faster than a pulse reflected from the drip tray and the bottom of the cup.
  • the drip tray or grate pulse is labeled DT, and the pulse reflected from the bottom of the cup is indicated LL in graph A; and as illustrated, they are adjacent since the drip tray surface and the cup bottom are closely juxtaposed. Thus, signal LL in this position indicates an empty cup.
  • FIG. C there is illustrated a full cup condition in which the liquid level pulse LL becomes contiguous to the cup lip pulse CL. Because these respective signals essentially merge, ringing between these signals can occur in the detector circuitry. Accordingly, in accordance with a preferred embodiment of the present invention, it is preferable to attempt to detect the leading edge of the cup lip signal CL labeled a and the trailing edge of the liquid level signal labeled b to avoid this ringing problem. This absence of a detectable trailing edge, a, of the lip signal, which would be the case in graph C, means that the cup is nearly full.
  • Microprocessor 34 is programmed to recognize such a condition and reinitiate the flow of liquid by generating a valve open signal along line C to the dispenser controls 20C until the liquid level signal LL moves back into juxtaposition with the cup lip signal CL. When this occurs, the microprocessor will again sense this condition and generate a valve closing signal along control line C to dispenser controls 20C, stopping the filling operation and achieving a full condition. Accordingly, a full cup of beverage can be obtained, regardless of the formation of a head of foam thereon, according to the techniques of the present invention.
  • graphs D and E there is illustrated the technique of the present invention for determining if there is too much ice within the cup 24 to initiate the filling operation.
  • graph D there is an acceptable level of ice because, as can be seen from a time axis analysis, the level of ice illustrated by the liquid level signal LL is disposed less than halfway towards the cup bottom.
  • the logic within microprocessor 34 is programmed to automatically initiate the filling operation by generating an initiate pulse along line C to dispenser controls 20C, to open the appropriate valve associated with a dispenser nozzle 22.
  • the ice level is such that the signal LL occupies the position on the time axis illustrated in graph E, this signifies that the cup is more than half full of ice.
  • the logic programmed into microprocessor 34 will not generate and initiate a signal along line C to dispenser 20C and the filling operation cannot begin. Accordingly, the system of the present invention will not permit an operator to overload a cup with ice and provide a customer with less than a predetermined amount of liquid beverage.
  • the Main Routine illustrated in Fig. 9 is responsible for testing of the microcomputer system and transducers, and then directing control to the seven different states or subroutines So to S6. Testing consists of the following:
  • Control functions are performed by calling the state that is selected. Each state is responsible for changing the state, to the next appropriate state, upon completion of its routine.
  • State ⁇ (S ⁇ ) illustrated in Fig. 10 is responsible for detecting the presence of a cup. If a cup is detected, the state is changed to Sl; otherwise, the state remains S0.
  • the first and second reflected signals read are saved for later reference.
  • the first value should be the lip signal and the second value the ice level signal for a cup with ice therein.
  • State 1 (Sl) illustrated in Fig. 11 is responsible for verifying the cup's presence and checking the ice level. If the cup's presence is verified and the ice level is okay, then the valve is turned on and the state is set to S2. If the cup is not verified then the state is set to S ⁇ . If the ice level is greater than allowed, a light indicating this will be lit. Cup presence verification is achieved by initiating a series of three ultrasonic pulses and detecting the receipt of at least 2 cup lip signals CL approximately equal to the lip value of CL saved in state S ⁇ .
  • State 2 is responsible for the initial filling of the cup.
  • the microprocessor software first looks to see if a cup is present and, if so, state 2 (S2) proceeds. It then looks to see if the second value (second reflected pulse detected) is equal to the grate value DT (this condition is illustrated in graph A of Fig. 8). If so, it then looks to see if the first value detected is equal to the lip signal CL plus an offset. This condition is illustrated in graph C of Fig. 8.
  • the offset (distance between a and b in graph C) is caused by the merging of the cup lip and the liquid level signals. When this condition is achieved, the cup is full and the software enters state 3 (S3).
  • the State 3 (S3) subroutine illustrated in Fig. 13 is responsible for reinitiating the filling of a cup after the foam dissipates. As illustrated in graph C of Fig. 8, when foam dissipates the liquid level signal subsides, for example to point c. State 3 (S3) begins with the dispenser valve off. It then reads both the lip and liquid level signals and, if the liquid or fluid level signal plus the offset (caused by the merging of CL and LL in graph C) is greater than the lip signal CL, the dispenser valve is turned back on to complete the filling of the cup. The main routine then moves on to state 4 (S4).
  • State 4 illustrated in Fig. 14 is responsible for finishing the filling that S3 was unable to complete.
  • the valve is turned off and the state is changed to S5.
  • State 5 (S5) illustrated in Fig. 15 is responsible for ensuring that the cup is full after the foam settles and detecting the removal of the cup. If the cup is determined to need more fluid, then the valve is turned back on and the state is changed to S4. If the cup is not detected, the state is changed to S6. If the cup is full and is detected, then the state is unchanged.
  • State 6 illustrated in Fig. 16 is responsible for verifying removal of the cup. If the grate level is detected, then the state is changed to S0; otherwise, the state is changed to S5 to ensure that the cup is full.
